SAN JOSE, Calif. — (BUSINESS WIRE) — June 16, 2009 —
Fairchild
Semiconductor (NYSE:
FCS) brings designers of 3G
smartphones,
netbooks,
set-top boxes and
notebooks
the industry’s first image module switch that isolates parasitic
components to maintain signal integrity. The
FSA1211
is a 12-port, single pole, single throw (SPST) analog switch that
isolates the high speed bus from parasitic components in dual camera
applications. Smartphones feature dual cameras and as these cameras move
to higher and higher resolutions, parasitic components play a critical
role in deteriorating signals and generating unwanted EMI.

With a bandwidth in excess of 720MHz and high ESD (5.5 kV), the
FSA1211
offers an optimal way to isolate capacitance and maintain signal
integrity for high speed data paths. In addition, when isolating the
unused parallel interface, the
FSA1211
reduces the radiated EMI of the path, improving RF desense. The
traditional parallel solution can deteriorate the signal due to the
unwanted “stub,” resulting in image degradation of the camera module.
Another approach is to use three
analog
switches, which complicates design and adds to the overall bill of
material (BOM) costs. In contrast, the
FSA1211
offers robust isolation and ease of design at a lower cost.

The
FSA1211
complements Fairchild’s comprehensive offering of
switch
products used in
portable
and
consumer
applications. These
analog,
audio, video and
USB
switches are instrumental in minimizing redundant circuitry,
eliminating connectors, simplifying design and conserving space in
designs. Offered in a variety of functions, configurations, packages and
performance levels, Fairchild’s switches are pivotal in solving portable
and consumer design challenges.
